16-Bit images to 8 bit images

Hello my name is Enrique, I am student from the Masters Degree Program in Medical Physics of the National Politechnic Institute in Mexico City.

I work with lots of medical images, creating algorithms to perform authomatic segmetation of organs. Actually i'm working with liver segmetation on children. I use Gimp to normalize my images but since they are on 16-bit Gimp authomaticaly convert them in 8-Bit, but as expected i loose data on that step.

Can you help me to understand how does Gimp perform this conversion? It will help me a lot :D.

Thank you so much,

sincerly

Enrique B.

currently published gimp is 8-bit, not 16 and does not operate/save except 8-bit. I believe unstable 2.9+ (or 2.10) does 16-bit.

It does. And 32bit. And 16/32/64 bit float. And linear light as well as perceptual light.

Bye,
